There are 3 things I do not do when dealing with "the public". I also don't do them at work, and I don't do them in my relationships - in fact, the only time I do them is when being sarcastic at friends. If you also stop doing this these things then you too will be a better person Walter:
You destroy trust and confidence in you by doing these things. Try taking ownership of your problems instead, by owning them you are responsible, and by being responsible you resolve them. Ever heard of a "responsible" person. Well if you are going to organise an event for the public you need to be responsible.
You cant turn around a day before the kart meeting and say "They put me behind bars, the whole thing is off.". Plains will still fly, money will still get charged. The ripple effect of you stealing the other in-mates pencil and using it as an anal brush will have dramatic consequences for maybe 30 people as they all try to figure out what to do with 2-3 day holidays to Holland, possibly a hotel and so on.
People who live within Holland will still have time off work, possibly limiting the number of days they have available when someone responsible tries to organise an event down the road, resulting in nobody available for the event until the following year - lowering quality of life, and leading to teen suicides.
Everyone from air stewardesses to hotel owners to taxi drivers to cafe chefs will be effected by the lost trade, plunging the Netherlands into a recession that could take the rest of Europe with it.
And it'll all be your fault.
Are you seriously locked up in a padded cell and yet still think you are responsible enough to run a European karting event? I am curious to know, because i'm wondering if you are in for some form of megalomania. If you are, then my post really hasn't helped.
But the opening bit, the bit about blame, excuses and denial - i'd take that with you for the rest of your life. It'll go a long way to earning respect.
